Google's Sergey Brin and his wife Anne Wojcicki donated $500,000 to help keep the popular Wikipedia online encyclopedia free of advertising.

The large donation comes after Wikimedia
Foundation kicked off its 8th annual fundraiser Nov. 16.
"This grant
is an important endorsement of the Wikimedia Foundation and its work, and I
hope it will send a signal as we kick off our annual fundraising campaign this
week," said Sue Gardner, executive director of the Wikimedia Foundation.
"This is how Wikipedia works: people use it, they
like it, and so they help pay for it, to keep it freely available for
themselves and for everyone around the world. I am very grateful to Sergey Brin
and Anne Wojcicki for supporting what we do."
Over the last decade, Wikipedia has become the fifth most popular Website in the world, with some 477 million unique
visitors a month, according to comScore. Despite it's global reach, Wikipedia
is operated by a modest staff and boosted by collaborators all over the world
who help make it available in more than 280 languages.
The service, which is also facing a huge backlog of editorial work, relies on donations to keep afloat and an
image of Founder Jimmy Wales asking for donations often appears at the top of
the Website's pages.
Wales, whose latest
message noted that everyone who came to Wikipedia donated $5 the funding would
be over in a single day, wrote an appeal letter:
"Google might have close to a million servers. Yahoo
has something like 13,000 staff. We have 679 servers and 95 staff. Wikipedia is
the #5 site on the Web and serves 450 million different people every month -
with billions of page views. Commerce is fine. Advertising is not evil. But it
doesn't belong here. Not in Wikipedia."
Wales' point is that in order for Wikipedia to keep
operating freely without taking money from advertisers, which would love to
spread their brand messaging across Wikipedia's well-trafficked pages, the
Wikimedia Foundation requires donations to keep paying the staff and keep the
lights on.
Hence the importance of Brin and Wojcicki's large grant, which comes after Google donated $2 million to help keep Wikipedia running in February 2010.
Brin and Wojcicki, who co-founded genetics company
23andMe, offered the funds under the banner of the Brin Wojcicki Foundation,
an organization that funded the Michael J. Fox Foundation, which is
researching a cure for Parkinson's disease.
Through 23andMe, Brin learned he has
a genetic predisposition toward Parkinson's disease, a fact about which wrote
about on his personal blog in 2008.
